It would be great to have a feature that enables an editor to select a portion of video and automatically identify any duplicate adjacent frames within the selection.

For example, when I'm editing a video with motion in it and want to minimize the number of frames in the sequence, I have to look at each frame and decide if there is any difference between it and either adjacent frame. I'll then manually delete frames with identical content such that only one frame remains with the content.

If there was a feature that would compare each frame within a predetermined range and automatically identify any frames that are identical to their adjacent frame, that would save a lot of time in editing.

Yes, but I've found that for the content in question, removing frames is more effective at producing more even scrolling. Scrolling involve acceleration and deceleration and what would really be needed would be a Clip Speed setting that reverses it, which Camtasia doesn't have. The current tool is purely linear.
